Earlier this year I bought a used camera (Sony DCR-TRV9) and housing (Quest Tiburon UDH-1S) with the thought that I would play around with a cheap used setup for a while to determine whether underwater video was something that I wanted to pursue. So far, it's been a long eventfull year and I've only done a fraction of the dives that I normally do in a year. I finally got everything squared away with the camera and housing and got to take it for a dunk last weekend. It was definitely an interesting experience and I'll probably play around with this setup for another year or so before I buy something a little more new. 
Here is my first video (Well actually second video. Same footage, but second attempt at editing):
Are there any tips that you guys can provide?
What is the effective range for a red filter? (I wasn't using a red filter for the video that I shot.)
Are there any other odd balls that using something other than Windows or Apple to edit video? I use Linux full time on my personal computer and currently using Kino to do the editing. I've played around with Open Movie Editor, but it doesn't appear to be stable right now. If you're using Linux, what editing software are you using?
